Nice homestay near Don Mueang Airport. Half or full day shopping/leisure trips to the new huge Future Park Rangsit, IT mall, Pak Kret etc are possible with bus rides from outside the airport. Also historical/cultural trip from Pak Kret to Koh Kret, an island in Chao Phraya River. The railway station is opposite the airport for those who want to travel north beyond Bangkok.
If you walk to Kru Ae's home, you will bypass the railway station, pass a Thai Buddhist temple, and see shops, food stalls, markets, motorcycle taxi stands, and other homes in a busy neighbourhood. Great for local sightseeing. Or, you can do as the locals often do: sit a super-cheap licensed motorcycle taxi from the food stalls opposite the airport for a short ride to Kru's house.
Kru enjoys hospitality. His home is clean and has a small lively nature setting outside the house. I had a nice Thai dinner conjured by Kru, of white rice with mixed vegetable soup, egg omelette, sardine with spices, and some dessert. The room was comfortable, the wifi was okay, toiletries were available, and the hot shower was good. Can engage Kru in lively conversations, or join him to watch local TV in his living room if possible.
I went for a morning walk with Kru, and watched the locals purchasing their breakfast and groceries in the morning market, giving their alms to monks and receiving blessings, doing exercises to keep fit, etc. Kru also chatted with some locals, who were curious and pleased to see a foreigner tourist in their midst.
Nice experience staying with Thai teacher at his home in his neighbourhood. Thank you Kru (Teacher) !
